In this paper
the overview of a level of study of the deformation processes on long-term petroleum
field development and ecological consequences accompanying them is given. In
more details these processes are considered for the oldest Absheron petroleum
bearing region (Absheron p-la, Azerbaijan) where fields are strongly depleted
and the pressure drop reaches 80% from initial values. Ecological consequences
of this phenomenon are the following: development in area of petroleum fields
Balakhany-Sabunchi-Ramany, Surakhany, Garachukhur, Bibi-Eybat intensive process
of ground subsiding (up to 47 mm/year) and flooding, frequent incidences of
curved boreholes, breaks in oil, gas, and water pipelines, and sudden kicks of
water and sand, occurrence of the induced seismicity (Surakhany earthquake in
1937 with magnitude 6). With purpose of forecasting of geodynamic processes creation
on petroleum production complexes of system of the environmental control is
recommended.
